Johnson shared photos of himself holding a bag of straw-colored liquid

Bryan Johnson, a millionaire technology entrepreneur committed to reversing aging, recently took to social media to brag about his “super clean plasma.” In a detailed article on

Johnson claims to have reduced his epigenetic age through his comprehensive program called Project Blueprint. He follows a strict diet and exercise routine, spends over $2 million annually on a medical team and medical equipment, and undergoes both experimental and conventional treatments – including the recent TPE procedure.

TPE, a procedure commonly used in regenerative medicine and anti-aging treatments, involves replacing a patient's plasma with donor plasma or a replacement fluid. In Johnson's case, his plasma was replaced with albumin.

He explained on

Completed my first total plasma exchange (TPE). I remove all the plasma in my body and replace it with albumin.

This is different from what I did last year: removing 1L of plasma from my body and then replacing it with 1L of my blood boy's plasma @talmagejohnson_ . I gave… pic.twitter.com/mrKsKt3zrg

Mr. Johnson proudly recounted that a clinic employee described his plasma as the “cleanest” they had seen in nine years of performing TPE. “The doctor who has been doing TPE for nine years said my plasma was the cleanest he had ever seen. By far. He couldn't get over it. When we finished, he couldn't bring himself to throw it away. That was him.” “I imagine how much good it could do in the world,” Johnson wrote.

The entrepreneur, who claims to have reduced his epigenetic age by 5.1 years, called his plasma “liquid gold” and also mentioned that his father's aging rate decreased by 25 years after receiving one liter of his plasma.

Mr. Johnson shared photos of himself holding a bag filled with a straw-colored liquid to document the experience.

Previously, Johnson made headlines for using his 17-year-old son in a “world's first intergenerational plasma exchange.” He clarified that this time, instead of his son's plasma, his own plasma was replaced with albumin.
